The battle with mastitis has always been an on-going, difficult challenge for the dairy producer. Research shows that in addition to the $150 economic loss per diagnosed case of mastitis from discarded milk, antibiotic treatment, decreased production and time spent managing treatment, mastitis also takes a toll on the dairy cow’s reproductive success.

Several studies support the detrimental effects of mastitis, including research¹ from the University of Tennessee. This study’s objective was to identify the presence and strength of the relationship between mastitis and reproduction within a 758-cow Jersey herd. Reproduction data was collected and analyzed over a 10-year period.

Cows diagnosed with mastitis experienced significantly greater days open and services per conception compared to cows with subclinical or no mastitis. Furthermore, cows with subclinical infections that eventually became clinical cases during the breeding period were most affected. Click on the link below for more information.
